Key Technology Coverage

The laboratory supports the full lifecycle of microgrid design and operation across three specialized domains:

• System Design and Simulation: Load analysis, renewable energy assessment, power and storage system configuration, and economic evaluation.
• Energy Storage System Configuration: Rated storage power is designed to meet maximum load instantaneous startup demands in off-grid mode, with capacity scaled appropriately for high motor/inductive device loads.
• EMS Integration: Robust Modbus-compatible energy management system, continuously updated to support new grid equipment and controllers.

The laboratory drives the maturation and practical deployment of microgrid technologies, delivering cutting-edge solutions for complex energy scenarios.

Core Positioning and Testing Capabilities

The laboratory's core function is the rigorous experimental validation of critical equipment such as power conversion system (PCS). A crucial test is the zero-second switching test, which simulates extreme grid outage events. This test verifies whether the PCS can seamlessly transition from grid-connected mode to off-grid mode, ensuring uninterrupted power supply to critical loads.

• Intelligent Isolation: Precisely detects grid faults and immediately sends signals to control circuit breakers, guaranteeing that the off-grid system operates independently and safely.

What is Real 0 Sec Seamless Switching between grid tied and off grid?

Real 0 Sec Seamless Switching between grid tied and off grid is a critical aspect of microgrid operation. It refers to the ability of the microgrid to switch from grid-connected mode to off-grid mode, and then back to grid-connected mode, without any interruption in power supply. This is achieved through the intelligent control of the power conversion system (PCS), which is equipped with advanced algorithms to detect grid faults and immediately send signals to control circuit breakers, guaranteeing that the off-grid system operates independently and safely.
